  • Analog/SDI to SDI/Optical Converter with TBC/Frame Sync User Guide
    Analog/SDI to SDI/Optical Converter with TBC/Frame Sync User Guide ENSEMBLE DESIGNS Revision 6.0 SW v1.0.8 This user guide provides detailed information for using the BrightEye™1 Analog/SDI to SDI/Optical Converter with Time Base Corrector and Frame Sync. The information in this user guide is organized into the following sections: • Product Overview • Functional Description • Applications • Rear Connections • Operation • Front Panel Controls and Indicators • Using The BrightEye Control Application • Warranty and Factory Service • Specifications • Glossary BrightEye-1 BrightEye 1 Analog/SDI to SDI/Optical Converter with TBC/FS PRODUCT OVERVIEW The BrightEye™ 1 Converter is a self-contained unit that can accept both analog and digital video inputs and output them as optical signals. Analog signals are converted to digital form and are then frame synchronized to a user-supplied video reference signal. When the digital input is selected, it too is synchronized to the reference input. Time Base Error Correction is provided, allowing the use of non-synchronous sources such as consumer VTRs and DVD players. An internal test signal generator will produce Color Bars and the pathological checkfield test signals. The processed signal is output as a serial digital component television signal in accordance with ITU-R 601 in both electrical and optical form. Front panel controls permit the user to monitor input and reference status, proper optical laser operation, select video inputs and TBC/Frame Sync function, and adjust video level. Control and monitoring can also be done using the BrightEye PC or BrightEye Mac application from a personal computer with USB support.

I. INTRODUCTION 1.10 or UHF channels in the United States, slotted antenna 1.09 designs are typically used [1]. A primary factor in their use F 1.08 has been the ability to make the support structure of the antenna an integral part of the transmitting components. Because the 1.07 frequencies assigned to UHF allow the use of relatively small 1.06 antenna elements, the removal of part of the pipe wall to create 1.05 slots was possible with only a minimal impact an its structural VSWR integrity. This resulted in an antenna with low wind-load 1.04 characteristics and was relatively economical to fabricate. 1.03 As television markets expanded, demographics changed 1.02 and competitive pressures fostered the need for UHF stations to increase their coverage. This required higher effective radiated 1.01 1.00 powers (ERP). And as higher power transmitters came to 572 574 576 578 580 582 584 market, other benefits unique to the slotted antenna design Frequency (MHz) became evident: exceptional reliability even at extremely high Figure 1: Dual Channel Antenna VSWR input power levels and more precise control over the shaping of the elevation pattern.

  • Video Distribution Amplifiers
    www.vac-brick.com Video Distribution Amplifiers What is a Distribution Amplifier? A Video Distribution Amplifier, or "DA" takes a single baseband video input signal and generates copies of that signal to drive multiple outputs. VAC’s DAs are active devices: the output signals are amplified and buffered, so that the signal quality on any of the outputs does not degrade when addi- tional devices are connected to the DA. Why Use VAC Video DAs? VAC is the market leader is delivering exceptionally compact, reliable, and high-quality video distri- bution amplifiers for broadcast, professional AV, security, military, and manufacturing applications. VAC offers an array of options to ensure that we can deliver the product that meets your exact needs. VAC video DA products incorporate the following valuable features: • True 75 Ohm BNC connectors provide accurate matching to coax cable input and outputs; also available with RCA connectors. • Sophisticated power supply circuitry to eliminate interference from noisy or poorly regulated power sources. • Exceptionally flat gain characteristics across the entire bandwidth to provide the highest quality signal reproduction • Epoxy encapsulated "Brick" is virtually impervious to environmental extremes. VAC DA products are available for the following video signal formats: • Composite (NTSC or PAL) Pages: 7-9, 17-18 • Quad DA Pages: 10 • DVRx Pages: 11-14 • Composite Video EQ DA Pages: 15-16 • Y/C (S-Video) Pages: 19-20 • Component (RGB, RGBs) Pages: 21-22 • High Definition Component Video Pages: 23 • SDI Digital Pages: 24 Depending on the signal format and model chosen, DAs are available with up to 16 outputs; unity, global variable, or individual variable gain; and standard, differential, loop-thru, or loop-thru differen- tial inputs.
